wk 2 4 intestinal failure COPY Flashcards
define intestinal failure
inability to maintain adequate nutruition or fluid status
what ca cause IF
obstruction dysmotility surgical resection congenital defect disease
characteristics of IF
inability to maintain protein-energy
fluid
electrolyte
micronutrient balance
example of acute IF
mucositis
post chemo
IF can be divided into 3 types
1 - self-limiting short term, post-op, paralytic ileus
2-prolonged,associatd with sepsis/metabolic coomplications. (surgery)
3-long term but stable, home parenteral nutrition
parenteral
nutruition delivery via IV
surgical ileus
stopping of peristalsis post-op
associated GI problems of IF type 1
vomiting dysphagia pancreatitis obstruction diarrhoea oncology - chemo, bone marrow transplant
asssociated conditions of type 2 IF
(post-op usually) trauma chrons SMA radiation adhesions- inflammatory fistulae (part of Chrons)
associated conditions with type 3
short bowel syndrome chrons +/-SBS Radiation +/- SBS dysmotility malabsorption Inoperable obstruction
when would parenteral nutrition be considred for ttype 1
after a week
treatment for type 1
acid suppressioin: proton pump inhibitors
octreotide
alpha hydroxycholecalciferol
diet/enteral feeding
define short bowel syndrome
insufficient length of small bowel to meet nutritional needs without artifical nutritional support
circumstances when parenteral nutrition is not required for type 3
over time adaptation occurs
if small bowel about 50 and long colon
what would be given if patient has <50cm/51-100/101-150
0-50 -parenteral saline/nutrition
51-100 parenteral saline nutrition-oral/enteral
101-150 oral/enteral OGs (Oral glucose saline) nutrition - none
